That’s superb but like you say ground rent and short lease is a putter offer .
If you had spare cash and knew you weren’t going to live more than 70 years at time of purchase it could be good.
But then Wood Green is shite (when I lived there in 1993 it was) but may have been delified now

Ground rent is unfortunately a little on the high side.
